Anyone know if your average shop has the ability to flow test fuel injectors or if it's more of a specialty shop thing? I've got a handful of fuel injectors in a box in the garage and I'd like to know what they're all rated at and if they are still actually making those numbers (some stock, some aftermarket)

 

Witchhunter does it and it's a specialty shop thing.

 

yes you need to find a shop that does fuel injector servicing. they need a stand that has a duty cycle power source, a container to measure the amount of fuel produced and a system to seal the injectors. not every joe schmoe shop has an injector service machine to do this, find an injector shop, most larger cities have one and even some smaller ones.
